Todd
What Todd is
Todd is a crater — a circular depression, almost always an impact scar — on Phobos, 2.6 km across, centred at 9.0° S, 153.0° W. It is the 11th largest named feature on Phobos and the 8th largest of its class there.
Where the name comes from
David; American astronomer (1855-1939). The International Astronomical Union approved the name in 1973, under the theme it applies to every crater on Phobos. Of the 17 features of this class catalogued on Phobos, the naming categories run Ireland (8), American (5), France (1), Germany (1).
What it would take to settle Todd
Phobos scores 48.7 as a world. That number is the same for every square metre of it — but sunlight, water, radiation and the ground under your feet are not. This is the same question asked at 9.0° S, 153.0° W.
What this spot has going for it is sunlight — 99% of the sunlight the sunniest latitude on Phobos gets. What works against it is water — same as everywhere else on this world.
Computed from Todd's catalogued latitude, longitude and feature class — 68% of the model's weight had a basis here, and 3 axes were dropped as not applicable to Phobos (radiation geometry, earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Phobos and are already counted in the world's own index, not again here.
What this cannot see: elevation. Slope, local shadowing and the polar “peaks of eternal light” — ridge tops near the poles of a barely tilted world that catch sun almost continuously while a crater floor kilometres away never does — need a terrain model this does not have. Where a real mission targets a pole, that is usually why.
